i Application :filed March 11, 192,4. Serial No. 698,545.

To all lwhomvft may concern.'

Be lit known that I, AnsALoM F. PneusoN, a citizen of they United States, resid-l ing at Mountain View,`in the county or ,Santa Clara and State of California, yhave `invented certain new and useful Improvefments in` 1ncubators,of which the followingis a specilication.

This invention relates to incubators Jr`or hatching `baby chicks, who, when hatched must not be iieduntil they are from tortyeight to seventy-two hours old, or before their yolkisabsorbed after being hatched, whichA will take care of them in the interim, because it sofed they will not absorbv the said yolk and digest food at the `same time, and will therefore die.

The general .object Y of my .invention is to provide an incubator in which the danger oiiteeding thehatched baby chicks before the proper time is eliminated.

. Minore particular object is ,to provide janincubator in which the baby chicks first hatched maybe separated from, and be re moved tromthose hatched later, so that the .latterhatched baby chicks may be fed a dayor two after those irsthatched, as .thecasemay be. 1

V.Other objects and advantages [will be made manifestl in the Jfollowing specification for-.an embodiment ol the invention illustrated "in the accompanying` drawings,y in `which: ,f f

Figurel is a frontelevation of the incubator. t y.

Figure `2 is a transverse vertical section of the incubator taken on line 2-2 of Figure 1. t

Figure 3 is a vertical longitudinal section of the incubator' taken on line 3-3 of Figure 2.

Figure l is a horizontal section taken on line 4.-4 of Figure 3.

Figure 5 is an enlarged fragmentary cross sectional view corresponding to Figure 2, illustrating the door construction between the egg chambers and the lower nursery chambers.

Figure 6 is a cross section of one of the lower nursery chambers, showing a modified means of heating the same.

Figure 7 is a view of a detail.

Referring in detail to the drawing in which like characters of reference designate similar parts, 1 indicates an incubator casing mounted on legs 2, tion and a transverse vertical partition ,4 divide the casing 1 into two egg chambers or yupper nmseries 5 and twolower chambers or .nurseries G, andI egg trays 7 are slidably mountedin the chambers 5`on slideways 8. y

Openings 9 are `provided in the partition 3 `a short distance rearnf'ardly of the front oit .the casing 1,`thesaid partition 31 between the front of lthe casing 1 and the openings 9 forming shelves 10 direetlybelow the outlet openings 11, in the bottom or' the trays at the front of the said trays, onto .which shelves the iirsthatched baby chicks may drop` from said egg trays through said tray openings, aftervwhich the chic rs may drop through said openings 9 into the lower nursery chambers 6. vSoft pads` 12 may be `placed Von the shelves 10 for the chicks to fall upon to prevent in- `iury of the said chicks. Doors 13 for closing the openings 9 are hinged at their rear edges to the rear edges of said openings by the `hinges r14,. and Atheir forward edgesl' are beveled to seat upon the beveled front edges 16 ot said openings, so that the doors will close tightly and Vopen easily, and when closed said ldoors will effectively shut oln the heat from the egg chambers to the nursery chambers therebelow.y The pivots 17 of the end hinges 14 extend throughthe end walls of the casing 1 and are bent at right angles at 18 outside the casing 1 and are formed with eyes 19 at their'extremities through which eyes the pins 20 may be inserted, and thence inserted into aper- Jtures 21 in the end walls of `the `said casing whereby the doors 13 may be held open so that the chicks may drop through the openings 9.

The drawers 22 slide into and out of the lower nursery chambers 6 through suitable doors 29 in the front of said chambers. The egg chambers 5 are heated by the usual lamp 25, or other heating means, and the said lamp may be mounted on the outside at one end of the casing 1, a heat duct 26 extends from the said lamp into said chambers, and bleed holes 27 may be provided in the partition 3 to allow a small amount of heat and air to escape from the egg chambers 5 into the nursery chambers 6 below to keep said chambers 6 warm and ventilated. The chambers 5 are cl-osed by the usual glass a horizontal parti- CII doors 28, and the lower nursery chambers 6 are closed by glass doors 29 in a similar manner, and suitable ventilators 23 are positioned in the walls of the incubator leading to the nursery chambers to furnish air to the chicks.

In the modified form of my incubator shown in Figure 6 the lower nursery chambers 6 are heated by a coil 30 which extends from the lamp- 25.

The operation of the incubator allows the first hatched chicks in the egg chambers 5 to walk to the front of the trays 7 where light is admitted through the glass doors 28, and drop through the tray openings 1l onto the shelf l0, from which the chicks drop through the openings 9 into the nursery chambers 6 therebelow and into the drawers 22 in said nursery chambers 6, the doors 13 being open, the drawers 22 are then removed from the nrusery chambers 6, the doors 29 being opened for tihis purpose, and the chicks are then placed in a brooder and may be fed at the proper time for the chicks lirst hatched. After the drop is closed to remove the chicks first hatched, the chicks hatched later may remain in the upper nurs ery until the said hatch is completed, or if so desired the drawers may be replaced and again removed with later hatched chicks at given intervals` Having thus described this invention what I claim is:

1. An incubator comprising an egg chamber, an'ursery cha-mberbelow said egg chamber', there being an opening in the wall dividing said chambers through which the hatched chicks pass from said egg chamber into said nursery chamber, means for heating said egg chamber and said nursery chamber, said dividing wall forming a shelf adjacent said opening in said egg chamber onto which the hatched chicks drop before dropping through said opening into the nurs- 'ery chamber below.

2. An incubator comprising an egg chamber, a nursery chamber below said egg chamber, there being an opening in the wall between said egg chamber and said nursery chamber through which the hatched chicks may pass from said egg chamber into said nursery chamber, an air tight door for closing said opening, a drawer in said nursery chamber for receiving the said chicks adapted to be removed from the said nursery chamber, egg trays slidably suspended in said egg chambers adapted to be removed therefrom, a Ventilating means extending through the wall between said cha1nbers,aheating means for heating t-he said egg chambers and said nursery chambers, as set forth.

3. An incubator of the class described, comprising an egg chamber, a nursery chamber below said egg chamber, an air tight door positioned in the wall between said egg chamber and said nursery chamber, an egg tray slidably suspended in said egg chamber, there being an opening in the floor of said egg tray through which the hatched chicks may pass from said egg tray onto the lower wall of said egg chamber forwardly of said door, a drawer in said nursery chamber for receiving the said chicks, there being bleed holes in the wall between said egg chamber and said nursery chamber, a heating means for heating the egg chamber, and a ventilator means for admitting fresh air into the said nursery chamber.

4f. An incubator comprising an egg chamber, a nursery chamber below said egg chamber, an egg tray slidably mounted in said egg chamber, a transparent door in the front of said chamber, the tray being provided with an opening in its bottom wall at the front thereof, the bottom wall of the egg chamber being provided with an opening rearwardly of said tray opening forming a shelf .of said bottom wall forwardly of its opening onto which shelf the hatched chicks may drop from the tray through the opening therein, and from which shelf said chicks may drop through said opening in said bottom wall into said nursery.

In testimony whereof I affix my signature.
